using DWNet.Data;
using System;

namespace Appeon.ApiDoc.IDataStoreExamples
{
    public class GetValuesExample
    {
        private readonly SchoolContext _context;

        public GetValuesExample(SchoolContext dataContext)
        {
            // Sets the data context
            _context = dataContext;
        }

        public void Example2()
        {
            // Instantiates a DataStore object with datawindow: d_department.
            var datastore = new DataStore("d_department", _context);

            datastore.Retrieve();

            // Gets the values of the name column.
            var names = datastore.GetValues("name");

            Console.WriteLine("Department Name:");

            foreach (var name in names)
            {
                Console.WriteLine(name);
            }
